A body moves due north with velocity 40 m/s. A force is applied
marshall27 [118]

Answer:

the direction of rate of change of the momentum is against the motion of the body, that is, downward.

The applied force is also against the direction of motion of the body, downward.

Explanation:

The change in the momentum of a body, if the mass of the body is constant, is given by the following formula:

\Delta p=\Delta (mv)\\\\\Delta p=m\Delta v

p: momentum

m: mass

\Delta v:  change in the velocity

The sign of the change in the velocity determines the direction of rate of change. Then you have:

\Delta v=v_2-v_1

v2: final velocity = 35m/s

v1: initial velocity = 40m/s

\Delta v =35m/s-40m/s=-5m/s

Hence, the direction of rate of change of the momentum is against the motion of the body, that is, downward.

The applied force is also against the direction of motion of the body, downward.

An object accelerates at a rate of 8 m/s² over a displacement of 9 m. If the object started with a velocity of 5 m/s, what is it
Crank

Answer:

13 m/s

Explanation:

The computation of the final velocity is shown below;

We know that

v^2 = u^2 + 2as

Here v represent the final velocity

u denotes the initial velocity

a denotes the acceleration

And, s denotes the displacement

So, the final velocity is  

v^2 = (5)^2 + 2(8)(9)

= sqrt(25 + 144)

= sqrt(169)

= 13 m/s

You use a very sensitive instrument to measure the speed of sound in your front yard in December. You repeat the test in August
frutty [35]
<h2>Answer: faster </h2>

The speed of sound varies depending on the medium through which the sound waves travel. In addition, it varies with changes in the temperature of the medium. This is because an <u>increase in temperature means that the frequency of interactions between the particles that transport the vibration increases</u>, hence this increase in activity increases the speed. That is why the speed of sound in a gas is not constant, but depends on the temperature.

So, if we want <u>the speed of sound in a gas to increase</u>, the<u> temperature</u> of that gas must <u>increase</u>, as well.

For example, the higher the air temperature, the greater the velocity of propagation. Experiments have shown that the speed of sound in air increases 0.6m/s for every 1\°C increase in temperature.

Therefore:

<h2>The speed of sound will be faster than in December</h2>
